The glass transition behavior of poly(diethylene glycol-co-succinic acid) (DEGSA) and its complexes obtained in the reaction with MgO have been investigated. The number average molar mass (\(\bar M_N \)) of the DEG-SA samples prior to complexation wa

The effect of metal ion content and thermal history on the crystallization and melting behavior of a semicrystalline low-molecular-weight poly(butylene adipate) and its Mg complexes was studied by wide-angle x-ray diffractometry and differential scan

Poly-(butanediol-1,4-adipate) and poly-(diethyleneglycol-succinate) polyesters and their “ionized” derivatives, containing Mg2+ and Zn2+ ions with different stoichiometric ratios to the chain-end COOH groups of the polyesters have been investigat

An increase in viscosity of reaction mixtures of low molecular mass, COOH, and alcoholic OH-terminated polyesters with MgO is considerably reduced by the presence of diols in the system. This effect is analogous with that described for the presence o

This article was written for the purpose of investigating the mechanisms of reactions between unsaturated polyester resins and base anhydridelike metal oxides (CaO, MgO, ZnO) which cause an increase in viscosity. As a model system ethyl-hydrogen-succ

Rheological properties of coordination polymers formed in the reaction of low-molecular-weight (about 1000) polyesters with MgO were studied. The melt viscosity and activation energy of viscous flow were measured as functions of Mg content and temper

The effects of chain-length of the diols and aliphatic dicarboxylic acids on the rate of polyesterification were studied. It was shown that the rate is only slightly influenced by the chain-length of the dicarboxylic acid. On the contrary, the reacti
